converting DateTime to unix time ?

thnx in advance...

Time.now

=> Mon Mar 17 13:51:00 -0700 2008

Time.now.to_i

=> 1205787064

Time.at(Time.now.to_i)

=> Mon Mar 17 13:51:18 -0700 2008

but if I already have a DateTime object how do I turn that object into
unix time ?
thnx again

a = DateTime.now
a. ?? (what method ?)

=> 12345678 (unix time)

a = DateTime.now
a. ?? (what method ?)

=> 12345678 (unix time)

d = DateTime.now

=> #<DateTime: 106036277450423033/43200000000,-7/24,2299161>

d.to_s

=> "2008-03-17T16:01:40-07:00"

d.to_time.to_i

=> 1205794900

Time.at(d.to_time.to_i)

=> Mon Mar 17 16:01:40 -0700 2008

I found this:
a = DateTime.now
Time.parse(a.to_s).to_i

but I'm pretty sure theres a better way to do it...

weird: 'udefined method to_time fo #<DateTime...'
?

Are you using rails? Or just ruby?

Everything I pasted in works for ruby 1.8.6, rails 1.2.5 via
./script/console.

before I tried with ruby (via irb).
now I tried it via the rails console I do this:

d = DateTime.now

=> #<DateTime: 106036277450423033/43200000000,-7/24,2299161>

d.to_s

=> "2008-03-17T16:01:40-07:00"

d.to_time.to_i

and now it claims - 'undefined method 'to_i' for datetime...'
ruby 1.8.6
rails 2.0.2

You're doing something wrong... or something isn't configured right...

$ ./script/console
Loading development environment (Rails 2.0.2)

DateTime.now.to_time.to_i

=> 1205797564

I believe u that it works for u, I mean, why wouldnt it ?
the question is why the hell will it not work for me...

the 'to_time' function returns a DateTime object and DateTime really
doesnt have a to_i method...
I guess the question is why to_time returns a DateTime and not a Time
object
